In order to increase thcl leverage in this construction, it'is necessary to increase the diameter ofthe gen1 which rolls on thc rack, hut the objection to this is, that n much ire/atar nmvcinent ot' Vth?v cui hofljv is nocessfiry in order to tilt i t through the anglo neccsssnrf to (lump it, und would thurs` carry it outside thcy wheels tending;l to tip ovni' tho Whole car.

It it be desired to dump the car body on il be necessary to move the cylinder l to its extreme left position without tilting the car body, which can be done by disconnecting it upon removing the key 34. Vhen. this inoveinent has taken place the key Re will be replaced in the slots 32' and 33 in such nianner as to engage the lett hand pin 35, whereupon the cylinder will n'love to the right and tilt the cai' body when power is adinitted upon the right h and side of piston 1S. ln the action olI the fore going parts, it will be seen. that the leverage increases the pin rises in the slot 35 until it reaches the highest point ot itsv arc and tl'ien decreases as it moves downward. in the slot passed the high point of the are. By suitably positioning the pins and calore lating the diameters of the gears relatively to the desired traverse of the car body, it will be seen that the leverage can be varied within. considerable limits.

lt is at tiines ii'npossible to secure fluid power to operate. the car body, and accordingly means is provided lor dumping the car body in anu ally.

40 is a shaft inounted in the framework having hand wheels 41, 41 and connected by 4:3, 43 with a gear #t4 mounted on a worn'i shaft 45, which latter shaft is inconted in a swinging frame 4G pivoted at 1.7 on the pedestals which carry the fixed pistons of the power cylinder and the controlling cylinder. `Normally, the trarne 46 is swung up so that the gear 44 is disengaged'troin the gear 43 and tbc worin 45 l'ren'i the gear wheel l1, but when itis desired to actuate the cai.' by hand the pin 4S is reinoved allowing the traine 46 to drop down and engage the worin 45 with gear l 1 and the gear 44 with gear 43, and the pin 45- en'gaging in another hole. When in this position, by turning the hand wheels 4l the gear 1l, will be turned and thus. the car body tilted.' Also, the checking cylinders will to control the inoven'ient in the saine manner as when'tl'ic power cylinder is used, in case the gears should break.

ln order to 'positively` lock the car body Si in central position it is provided with a lng 5U, which is engagml on opposite sides by a latch 5l (Figs. l and (i) pivolcd on the l'ranic l at :32. 'lhe latch is irnnle ol two parts so to be adjustal'ile on the shalt 52 towards and 'l'roni each otheiz lreterably, the latch 5l is over-weighted, and has two jaws inclined towards eachother so that it `.fill drop until the inclined jaws engage thc lug 5U. rlhc latch is adjustable so as to take care ot' variatioi'is in thc size and position of the lugs on the ladle. To operate thc latch 5l a hand rod 54 is provided extending rearwardly l'or convenient actuation. by the operator.

Fron'i the foregoing ,description i l l i l i l l l l l l i i has to travel, and thereby enabling the power to. be more el'l'ectively applied. Also, the stroke ci the inotor being longer than the bodily movement olL the car body, there vill be less power required. to secure the saine result, by reason ot the fact that thc power acts through a greater distance as well as leverage. By the construction of checking apparatus herein described, an adwintageous result in controlling the movement ot the car body is also secured, since the n'iovenient ot' the checking devices is likewise greater than the bodily nioveinent of the car body, `so that the retardation takes place through a greater (.listaiice. It `will also be seen that by means of the two pins and the interchangeable locking key, the body can be dumped on either' Side, but it should be understood that the inventioiii is not to be confined to such a construction, it is equally applicable to cars ot this general type dumping on one side only.

The construction herein described is susceptible of various inodiiicat-ions and changes without departing l'roin the scopeot thcinveiition, which is not to be restrictcd to the precise torni and detail herein illustrated.

Having thus described iny invention, l declare that what l claini as new and desire to secure by Letters Patent, is

1. rllhe combination with a car body and a supporting traine provided with racks lor tilting the ear body as it travels transversely oi' the support, ot a inotor inounled to actuate the cnr body, a gear carried b v the car,

2. A car body mounted to tiltl and travel l:i.rei'ail \,f, in con'ibination with a laterally traveling motor 'l'or imparting to the car its laterally traveling movement, nicans l'or tilting the car during its traveling niovenici'it, and a. pauuliy oi' eccentric. actuating conncctions carried by lhc car body, and interchangeable slotted means i'or directly connecting the motor with one or the othcrol said actuating connectioi'is, acrordingl to the direction in which the car body is to be moved l'roni a central position.
